View 2 RepliesWhen I try and populate a listview with data from an array with 3 entries I find that the data goes into the wrong columns. The array consists of the following.
?ID
{Length=3}
(0): "T123456789"
[Code].....
The scenario is i get a string sent to me that i split by a space. Any thing under 60 count when the split occurs it's fine. After that i have a problem.Now there is a lot that needs to happen before we can add this newly split array to the listview.First we need to check what the name starts with. Then assign an icon to this nick.When my server class gets sent this string. Raw Numeric 353 channel names i then send it to my nicklist class.
vb
Private Sub InitiateThread(ByVal nicks As String) Handles _server.NameListEventArgs
Dim thread As New Thread(DirectCast(Sub() DoWorkChannelNicks(nicks), ThreadStart))
thread.Start()
End Sub
Then we split the string and loop each item
vb
Private Sub DoWorkChannelNicks(ByVal users As String)
Dim nicks() As String = users.Split(" "c)

how to speed the process up?

View 2 RepliesI am wondering how to save a textbox contents to disk?? Using the MSDN help I was able to come up with this code so far. I have a menu strip item labled "save as." when I click it the prompt to allow you to pick a location to save comes up and it will save a text file to the selected location but the .txt file is blank. How do I set this code so that it knows to save the contents of the textbox.

I want webbrowser1 to navigate to a list of URLs that will be read in from a text file. (I left that part out of the below code and just manually entered urls as examples.) What I have found is that the webbrowser1 will navigate to the urls, but it will not stay long enough to get anything from them. In this example, not even the final page loaded ends up getting saved. Can someone tell me how to halt the attempt to save webbrowser1.documenttext until it is fully loaded?

View 1 RepliesI have a mySQL table(IMP_SCANS) holding the file, it's name and size for every document:
scan_1 blob
description varchar
filesize int
doc_no varchar
doc_date date
I managed to insert a file to the table. Now I need to save the file to disk.
So I have the code:
Dim conn As New MySqlConnection
Dim cmd As New MySqlCommand
Dim myData As MySqlDataReader
Dim SQL As String
Dim FileSize As UInt32
Dim fs As FileStream
[CODE]............
I all works fine up to the line: myData.GetBytes(myData.GetOrdinal("scan_1"), 0, rawData, 0, filesize) Where it says "Object reference not set to an instance of an object". I cannot figure out why I receive this error.

I have a program where you have three entries, CD name, artist, price and it goes into a listbox and .txt file when closing. I have to have a message box if you enter the same CD name. I have a code to open the .txt file and compare strings but I need to change it to compare only the CD name and not all three entries. Is there a way to do my string compare against my listbox without opening the .txt file?? The program loads the listbox from the .txt file when opening. Private Sub btnAdd_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAdd.Click' adds CD information to the list box
' declare variables
Dim strName As String
Dim strArtist As String
Dim strPrice As String

I want to set a certain column to true or false automatically based on what value another column has entered. I managed to get this working by myself using the 'SQL Pane' in VB and testing it by using execute sql but I don't know what to do now. I assumed that I could just save it and it would work from there but that's not the case, it dissapears from the SQL Pane if I close the project (even though it worked fine when I ran the project the first time), so where do I put it/what do I do with it in order to get this to work?
View 1 RepliesI was thinking to make an app to save images [or download images] to local hard disk. But to keep it easy, I want this app to create a small picturebox on form to show the thumbnail of downloaded image. Lets say a 5 pictureboxes has to be added with the thumbnails to show the recent downloads. A user can save the location where he wants to save the files on hard disk. A listbox or a dropdown menu will help in categorizing the images, like image1 in friends section, image2 in family section, image3 in others, etc... When the program restarts all the latest 5 thumbnails has to be loaded in pictureboxes and the directory that was chosen. Finally, a button that shows the downloaded images into original image file size one by one or a slide show. Is it possible to make such program?

What is the best way to save listview items?
View 3 Repliesi am currently working on an Application Manager that basically will free up my desktop of all my shortcuts by adding them to a program, or in my case, the listview object. Basically, so far i have set up a toolbar on top with a few options that will add listview objects, listview groups, remove those, and some other help and support things.
What i want to do is allow the user to add a listview object, which will be an application shortcut- they can choose the name, the icon, descriptions, whatever. (In essence, i am basically moving the desktop style of shortcuts into an application, where you can categorize and organize these shortcuts).
The questions i have are: 1. Is the listview object a good option for what i am trying to accomplish? 2. I saw that you can import imagelists, but how can i incorporate that to include icon pictures selected when a user adds an application? 3. How do you save listview data? 4. Anyone have a good strategy on how to approach this project? 5. Do i/Should i make an 'application' class that handles all the application information rather than using direct listview methods?
I have some problems again with listview. This time my problem is that my list view save wrongly to dll file. Like this ListViewItem: {TEST} . So loading load this at same form too and this thing dont work.

For x = 0 To ListView2.Items.Count - 1
savedata1.WriteLine(ListView2.Items(x))
Next x
savedata1.Close()
I hope that somebody knows how to fix it and can help me.
